Product Description for the QSC GX7 Power Amplifier

The GX7 professional power amplifier continues in the tradition of QSC's top-selling GX Series professional power amplifiers by offering an attractive combination of power, fidelity, configurability, long-term reliability, and overall value. At the heart of the GX7 is an all-new, advanced power supply based on the road-proven PowerLight Series technology. The result is a more overall power output in a lightweight casing compared to previous GX models—without any sacrifice in audio quality. At 1000W per channel at 4 ohms, the GX7 provides more than ample power to connect up to four 500W 15" 2-way speakers or two 1000W subwoofers at a time. This will help to keep your overall system cost down while still maintaining maximum performance levels. The 8 ohm output is 725 watts per channel which yields considerable headroom and increased dynamic range for today's popular loudspeakers.


  • Power levels matched to the most popular speakers
  • Optimized for maximum real-world headroom into 4 ohm and 8 ohm speaker systems
  • Inputs: XLR, 1/4" TRS and phono input connectors for compatibility with any source
  • Outputs: Speakon combo accepts, 1/4" (TS) plugs or Speakon 2-pole and 4-pole plugs (connects 2 poles only). Binding posts support all other speaker wiring systems.
  • Minimum depth chassis (10.1") fits in compact, inexpensive effects racks
  • Lightweight - less than 20 lbs.
  • Detented gain controls for precise setting and matching of sensitivity
  • GuardRail automatically protects the amplifier and loudspeakers from damage due to temperature rise or overdrive without shutting down the show

Great lightweight amp.
Review by DJ Stroud
Lightweight and compact amp great for mobile uses. Good price as well for such a quality amp. I have a couple, and this has become my most used amp. Lots of power for my bass bins/subwoofers, as well as full range speakers. A variety of inputs and outputs makes it really flexible. Crossover option is nice to have available, though I rarely use it, preferring to use my own. I also like the option of driving a single channel at 4 ohms to get 1200W out of it, which is nice for driving my 15" JBL subs rated at 800W continuous for gigs when I need some extra push. Worst I can say is, I would have liked more lights on the level meter, as are on the PLXs. The lights on the QSCs sometimes stop working after a while as well. (Posted on 12/3/12)

Review by Jack
I recently purchased two of these for FOH. One amp for each side running tops and subs. This is a very straight foward amp with ease of use. They have plenty of gain and are easily balanced thru the front controls. The clarity when using the xover is fantastic without any bleed thru. You could easily power a small system with one of them, 2 subs and 2 tops for a total of 2000 watts for medium clubs. One of the best investments I've made to date.
